[jira] Created: (HIVEMIND-122) URLResource: IBM JDK 1.4.1 and java.net.URL.openStream causes NPE
URLResource: IBM JDK 1.4.1 and java.net.URL.openStream causes NPE
-----------------------------------------------------------------
Key: HIVEMIND-122
URL: http://issues.apache.org/jira/browse/HIVEMIND-122
Project: HiveMind
Type: Bug
Components: framework
Versions: 1.0, 1.1
Environment: WAS 5.1 on AIX, IBM JDK 1.4.1, Hivemind
Reporter: Michael Frericks
Situation:
The BuilderFactory fails to set the message-property.
Reason:
While looping over all possible localized names of the message resource
there is a uncaught NPE for not existing resources.
In the method org.apache.hivemind.util.URLResource#getResourceURL()
the call of java.net.URL#openStream() is expected to throw an
IOException if the Resource does not exist.
But in described environment the method returns silently null and
then the next statement causes an NPE which is not caught.
Solution:
In the method org.apache.hivemind.util.URLResource#getResourceURL()
change:
...
try
{
InputStream stream = test.openStream();
if (stream != null)
stream.close();
_url = test;
}
to:
...
try
{
InputStream stream = test.openStream();
if (stream != null)
{
stream.close();
_url = test;
}
}

[jira] Commented: (HIVEMIND-122) URLResource: IBM JDK 1.4.1 and java.net.URL.openStream causes NPE

James Carman commented on HIVEMIND-122:
---------------------------------------
I don't know if I would consider this a bug in HiveMind or the JDK. The JavaDocs don't mention anything about a null return value being acceptable (doesn't mean that it isn't). We can certainly code around this and I will try to devise a test case that exhibits this behavior.
